SMARTCONSTRUCTION covers the critical steps in a project’s development, from initial site survey and design, through to machine control management, machine interconnectivity and review of project progress during the construction phase, and finally development of detailed as-built information for future construction and infrastructure maintenance.

Komatsu has launched its new KOMTRAX, a complimentary remote monitoring system that provides access to specific machine data and jobsite management via an improved interface.

At Komatsu New Zealand, we are always looking for good people to come and work with us. And with over 3000 employees across our Oceania operations (covering New Zealand, Australia and New Caledonia) we offer plenty of opportunities for career advancement.

Frame

FRONT FRAME STRUCTURE

Frames are articulated by two hydraulic cylinders. Box-sectioned front and rear frames are steel plate welded construction and connected with an articulation pin. One-piece-frame design for the front frame in which hydraulic piping is installed offering excellent front visibility for more precise operations.

Hydroshift Transmission

The Komatsu HYDROSHIFT transmission consists of planetary gears and hydraulically actuated and force-lubricated multiple-disc clutches, assuring light-touch, effort-minimising shifting. Both speed shifting and direction changes are completed by a single lever. With the inching pedal, precise finishing operation and smooth machine starts are ensured. A super wide range of 8 forward and 8 reverse speeds match all job requirements. Accidental machine starts are prevented by a gearshift lock device and engine starts only when the shift lever is set in the parking position.

GD825A-2
Motor Graders

Developed as a minesite support grader for both construction and maintenance applications, our 209 kW GD825A-2 grader features Komatsu quality and durability to deliver high productivity and reliability with excellent availability. As with all our graders, key components are designed and manufactured by Komatsu to work together in an integrated package.

High Stability

Weight distribution on the front and rear wheels is well balanced, particularly the large weight on the front wheels leads to less side slip and greater productivity under heavy-duty conditions. The GD825A-2 features a large blade force to easily penetrate the ground on tough haul roads, ensuring efficient grading operation with fewer passes.

Articulated Frame

A 25 degrees frame articulation gives the GD825A a minimum turning radius of 7.9 m, making it easy to maneuver in tight quarters. Three basic operating postures are available to meet your varying needs: Straight frame suitable for long-pass grading, articulated frame for tight turning and offset frame for locating drive wheels on prepared ground.

High Blade Performance

The operator can position the blade at the desired bank cutting angle up to 90 degrees on either side, without leaving the operator's compartment. The high blade rotating speed facilitates quick blade changes for increased productivity. A large shoulder reach and hydraulic blade tip control allow the operator to match the GD825A-2 to the most demanding applications.
